ABSTRACT:
Michael addition products of monocarboxylic or dicarboxylic acid esters, capable of undergoing Michael addition, with compounds containing double bonds capable of undergoing Michael addition are suitable for use as a curing component for synthetic resins containing groups capable of amide formation and/or ester formation with carboxylic acids. In particular, the Michael addition products of acetoacetic esters or malonic esters with esters, amides or urea derivatives of .alpha., .beta.-unsaturated monocarboxylic or dicarboxylic acids are used. The structure and the functionality of the curing component can be varied in many ways. It can be attached directly to the synthetic resin molecule, so that self-curing synthetic resins are obtained.
